Why does Li Bai use Cao Zhi's poems in Into the Wine?

Express your dissatisfaction. "What are bells and drums, delicacies and treasures? I hope I will never wake up. Ancient sober people and sages were forgotten, and only great drinkers can be immortalized. It is said that Chen gave a banquet in the completion hall and bought a barrel of wine for 10 thousand yuan, talking and laughing happily. "Zhong Gu Yu" refers to the life of a rich family. In ancient times, rich people feasted, the bells rang, and they ate like jade, singing and dancing to show their wealth, but in the eyes of poets, it was "not expensive enough" What he longs for is "I hope I will never wake up after being drunk for a long time", which is simply a drunken remark, a helpless remark and an angry remark, which is by no means true. When Li Bai was young, he had "Shen's talk, seeking the skills of the emperor, inspiring his wisdom, and willing to assist him to make the atlas area big and the county clear" ("Dai Shoushan answers the biography of Meng Shaofu"), so in the first year of Tianbao (AD 742), that is, when he was 42 years old, Li Bai got the imperial edict calling him into Beijing. At this time, Li Bai was forced to give up his official career because of the exclusion of the powerful people in the DPRK. He wrote in the poem "It's hard to walk" that "the road is as wide as the sky, and there is no way out at present", and the grievances that have been accumulated for a long time in his chest suddenly broke out. This is the true nature of Li Bai. If we compare this sentence to "I wish I stayed drunk for a long time", it is not difficult to see how depressed Li Bai was at this time. Besides being depressed, he had no choice but to find some basis and excuses to comfort himself: "Those who were sober in the past forgot all the sages", and only Wang Chen [Cao Zhi], who was good at drinking, left a thousand-year reputation. The implication is that good drinking is famous for later generations. It is in this extreme pain that his self-confidence and arrogance remain the same, and he is really a person through the ages.
